I want to change to value of the major and minor of my beacon by calling a shell script from a java code.
If for example I want to set the value of the Major to 39321, I have to pass a string with the value 99 99 as parameter to the shell code.
If I want to set it to 34866, I have to pass the hex code 88 32.
How can I convert from a long number like the 39321 to this two character composed hex number like 99 99?

Format it with "%x" is not enough ? – Serge Ballesta Jun 10 '16 at 09:33

Or `Long.toHexString`? – Jon Skeet Jun 10 '16 at 09:34

Long.toHexString will change 39321 to 0000000000000000000000000000003339333231 and not 99 99. "%x" is just for formatting it will also not change 39321 to "99 99" – Celiiine Jun 10 '16 at 09:45

You can use toHexString(long i) method from Long class.
For example :
Long.toHexString(39321)
It returns a string representation of the long argument as an unsigned integer in base 16.

This will return 0000000000000000000000000000003339333231, I am expecting to have 99 99 as result. – Celiiine Jun 10 '16 at 09:52

@Celiiine I got String result **9999** when testing with my eclipse. I am using **jdk1.8.0_72** and running on window 8. – Necromancer Jun 10 '16 at 10:02
